Colorectal Surgery Outcomes and Healthcare Burden for Medicare Beneficiaries With Dementia.
Article in The Journal of surgical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionPatients with Alzheimer's disease and related dementias (ADRD) undergoing colorectal surgery have suboptimal postoperative outcomes, but the specific adverse outcomes and the context of these worse outcomes on a national level are not well understood.
methodsColorectal surgery patients with and without ADRD from January 1, 2017, to October 1, 2018, were identified using traditional, fee-for-service Medicare claims data. Unadjusted and adjusted analyses were performed to evaluate postoperative outcomes.
results123,324 Medicare beneficiaries (mean age 76.5, 59.3% female) underwent colorectal surgery in the study cohort with 8.3% (n = 10,254) having a preoperative diagnosis of ADRD. Colorectal surgery patients with ADRD were older (81 versus 76 y old, P < 0.001), frail (42.8% versus 13.6%, P < 0.001), and had more comorbidities (Elixhauser Score 19.6 versus 13.9, P < 0.001) compared with those without an ADRD diagnosis. Patients with ADRD more often had open surgery (75.2% versus 65.7%, P < 0.001) and emergency surgery (65.1% versus 37.8%, P < 0.001). Unadjusted and adjusted analyses demonstrated that patients with ADRD have an increased risk of in-hospital, 30-d, and 90-day mortality, as well as postoperative complications. Patients with ADRD required more healthcare resources after colorectal surgery including increased length of stay (7 versus 5 days), discharge to a higher level of care (60.8% versus 25.8%, P < 0.001), and discharge to a facility (54.0% versus 23.8%, P < 0.001).
conclusionsFor patients undergoing colorectal surgery, the diagnosis of ADRD is an independent risk factor for adverse postoperative outcomes and results in increased healthcare resource utilization both in hospital and after discharge.
